I guess a school wouldn't turn down any extra bit of money but would be nice (within reason) if a student can grab a couple snacks for free now and then if they like study after school together or like part of a clubroom
(Although faking sickness aside you'd think they'd be scolded by the seller for buying a snack when it's not proper break time unless they're allowed to if ppl assume they're going to the bathroom and just buying something quickly [tho i would've half expected her to just bribe the principal directly], i mean i guess they did get caught but still)
Although i haven't had JP cream puffs but sometimes 'cream filling' can be hit or miss
